The music perfectly captures the slide from the wild party of Dos to the morning hangover of Tre. The apocalyptic end of W!TL is a sonic image of the party finally exploding out of control. The neighbors call the police, partiers are dragged away, the stereo is turned off. And then, as the lonely sound of Amy begins, you can see the last man standing, blinking neon lights casting shadows on his face as he eases himself down onto a nearby chair. He takes a look at the carnage around him--spilled beer, scattered trash, used condoms--and sighs at the thought of the cleanup to come. It's the only time in the Trilogy that I truly buy Billie's wankery about a "party concept" integrating the albums. So while there are better songs on the Trilogy, these two are the most successful, to me, in terms of communicating theme.
